Troubleshooting practice questions

You are troubleshooting a canvas app that loads slowly. The app uses over 50 data sources and many formulas. Which action is most likely to improve performance?

Trap 1: Increase the data row limit for each data source

Increasing row limit can slow performance.

Trap 2: Disable the formula-level error checking

Error checking does not impact app performance.

Trap 3: Remove unused data sources from the app

Unused data sources do not affect runtime performance.

A
Increase the data row limit for each data source
Why wrong: Increasing row limit can slow performance.
B
Use delegable queries to filter data at the source
Delegation pushes filtering to the data source, reducing data transfer.
C
Disable the formula-level error checking
Why wrong: Error checking does not impact app performance.
D
Remove unused data sources from the app
Why wrong: Unused data sources do not affect runtime performance.

Question 2hardmultiple choice

A developer is troubleshooting a canvas app that uses a SharePoint list as a data source. The app works for some users but fails for others with the error 'Access denied.' All users have read access to the SharePoint list. What could be the issue?

Trap 1: The SharePoint list is set to private

Private lists would not allow any read access.

Trap 2: The users do not have Power Apps licenses

License would prevent app access entirely, not just data.

Trap 3: The app is in a different environment than the users

Environment does not affect data permissions.

A
The users do not have permissions to the SharePoint list
Power Apps inherits SharePoint permissions; users need read access to the list.
B
The SharePoint list is set to private
Why wrong: Private lists would not allow any read access.
C
The users do not have Power Apps licenses
Why wrong: License would prevent app access entirely, not just data.
D
The app is in a different environment than the users
Why wrong: Environment does not affect data permissions.

Question 3mediummultiple choice

You are troubleshooting a Power Apps issue. Using PowerShell, you run Get-AdminPowerApp and see the exhibit output. What does the EnvironmentName field indicate?

Exhibit

Refer to the exhibit.
```
PowerShell cmdlet: Get-AdminPowerApp
Sample output:
AppName        : SalesPipelineApp
CreatedTime    : 2024-01-15T10:30:00Z
LastModifiedTime : 2024-06-20T14:00:00Z
Owner          : user@contoso.com
EnvironmentName : Default-12345678-1234-1234-1234-123456789abc
```

Trap 1: The license key for Power Apps.

License keys are different.

Trap 2: The name of the custom connector used by the app.

Custom connectors have different identifiers.

Trap 3: The name of the SharePoint site where the app is stored.

Apps are stored in Dataverse environments.

A
The license key for Power Apps.
Why wrong: License keys are different.
B
The unique identifier of the Dataverse environment hosting the app.
Each environment has a unique GUID.
C
The name of the custom connector used by the app.
Why wrong: Custom connectors have different identifiers.
D
The name of the SharePoint site where the app is stored.
Why wrong: Apps are stored in Dataverse environments.

Question 4hardmulti select

Which TWO are best practices for designing Power Automate flows in a production environment? (Select TWO.)

Trap 1: Disable flow logging to improve performance.

Logging is important for monitoring and troubleshooting.

Trap 2: Nest Apply to each actions to handle large datasets.

Nesting can cause performance issues; use parallel or pagination.

Trap 3: Hardcode connection references for simplicity.

Hardcoding is not a best practice; use secure inputs.

A
Disable flow logging to improve performance.
Why wrong: Logging is important for monitoring and troubleshooting.
B
Use 'Configure Run After' to implement error handling.
This handles failures gracefully.
C
Nest Apply to each actions to handle large datasets.
Why wrong: Nesting can cause performance issues; use parallel or pagination.
D
Hardcode connection references for simplicity.
Why wrong: Hardcoding is not a best practice; use secure inputs.
E
Use secure inputs and outputs for actions handling sensitive data.
Protects sensitive data in logs.

Question 5hardmultiple choice

You are troubleshooting a Power Automate flow that uses an HTTP action to call a REST API. The flow fails with a '429 Too Many Requests' error. The API has a rate limit of 100 requests per minute. Which strategy should you implement to handle this error gracefully?

Trap 1: Increase the flow's concurrency setting to process more requests…

More concurrency would increase rate limit hits.

Trap 2: Use a 'Condition' action to check the status code and ignore 429…

Ignoring errors would miss API calls.

Trap 3: Use the 'Configure Run After' option to skip the action on failure.

Skipping on failure does not retry.

A
Implement retry logic with exponential backoff in the HTTP action settings.
Exponential backoff reduces request rate after 429 responses.
B
Increase the flow's concurrency setting to process more requests simultaneously.
Why wrong: More concurrency would increase rate limit hits.
C
Use a 'Condition' action to check the status code and ignore 429 errors.
Why wrong: Ignoring errors would miss API calls.
D
Use the 'Configure Run After' option to skip the action on failure.
Why wrong: Skipping on failure does not retry.
